In the operation of the pipeline, according to the requirements of the operation of the corresponding series of pipe cleaning device. Clear edge tube cup and the inner wall of the pipeline elastic sealing, caused by pipe conveying medium pressure as the driving force to promote the Qing run along the pipeline tube. Rely on the pig itself or the machine with scraping and scouring action to clear the pipeline scaling or sediment. Is made of polyurethane raw material by the mold or foam plastic through the special equipment processing, the first end of the tube with a conical head of the garden, its external coating cross winding wear resistant layer or carbide of the hard wear-resistant belt. The core material is soft, easy to pass the 90 degree of curvature radius of the elbow, and the tube wall close fit, you can remove dirt and corrosion in the pipe and other impurities.
